    • The present invention is to provide a narrow bandpass filter installed on a circuit board for suppressing a high-frequency harmonic wave, which uses a metal microstrip method to directly build a microstrip circuit corresponding to a narrow bandpass filter on a circuit board of a wireless communication product and uses an interdigital finger method to lay a capacitor microstrip of the microstrip circuit on the circuit board to avoid the capacitor microstrip occupying too much area of the circuit board and maximizes the usable space of the circuit board, so that the wireless communication product can suppress a second or higher harmonic spurious noise of the wireless communication product without using an additional high-frequency filter, and thus can greatly lower the manufacturing cost of the wireless communication product and effectively reduce the electromagnetic interference.
    • 本发明是提供一种安装在用于抑制高频谐波的电路板上的窄带通滤波器,其使用金属微带方法在无线通信的电路板上直接构建对应于窄带通滤波器的微带线路 产品并采用叉指方式,在电路板上铺设微带电路的电容微带线,以避免电容微带占用电路板的太多面积,并最大化电路板的可用空间,使无线通信产品 抑制无线通信产品的二次或高次谐波杂散噪声,而不需要额外的高频滤波器,从而可以大大降低无线通信产品的制造成本,有效降低电磁干扰。
